Question

We have a filament-wound pressure vessel fabricated from E-glass/epoxy with the strength properties as listed below. The diameter d 1 m, and wall thickness 20 mm. The vessel is subjected to an internal pressure, p. The fiber orientation囝囝= 53 degree. Determine the maximum internal pressure p, which would cause failure of the vessel according to (a) the maximum stress criterion and (b) the Tsai-Hill criterion (no need to solve "b" - we will learn Tsai-Hill failure criterion from Chapter # 7). Strength values: FIt1 103 MPa, Fic 621 MPa, F2t 27 MPa, F2c 138 MPa, Fo 83 MPa.
